This problem is also showing up with our new PCs using the IT8728 (motherboard is Gigabyte Z87-D3HP). The watchdog is armed and the time-out can be set, but the "refresh" is not working so the machine reboots after the chip's time-out period.
Jul 2 16:57:04 kernel: [ 346.256483] it87_wdt: Chip IT8728 revision 1 initialized. timeout=60 sec (nowayout=0 testmode=0 exclusive=1 nogameport=0)
We are using Ubuntu 12.04.2 32-bit:

As far as I can see (e.g. http://tomoyo.sourceforge.jp/cgi-bin/lxr/source/drivers/watchdog/it87_wdt.c) there has been no updates to the it87_wdt driver since the 3.5 kernel, so it is still an open bug.
